Helix D FOUR
The new entry into the HELIX world! The amplifiers of the D series are solely modest with respect to pricing. Everything else is thoroughly pure HELIX quality without any compromises. Loads of power, excellent measurement data and a whole bunch of features ensure a pristine and crispy sound experience!
Absolutely nothing has been missed for powerful sound reproduction – the active crossover with highpass filter, lowpass filter, bandpass and bass boost are equally as self-evident as the intelligent highlevel input that incorporates Audiotec Fischer´s proprietary ADEP circuit. It is even possible to add an optional volume remote control for the amp channels C and D which is very useful if those outputs are firing a subwoofer.
The elegant design not only states right from the beginning the amp’s heritage but also allows an easy integration into your car thanks to its compact dimensions. That is sound-tuning at its best!

Helix M SIX
One for all – no matter if 3-way, 2-way or subwoofer application, the 6-channel amplifier M SIX will always be the right choice.
With generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load this amp really gets your speaker cones going despite its super-compact dimensions. On the other hand the M SIX stays totally cool thanks to its highly efficient Class D design topology. And even bridged configurations are possible, delivering up to 3 x 200 Watts RMS of clean and undistorted output power.
In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. And finally the perfect sound tuning is no big deal thanks to its integrated crossover with all its setup options. -
Match M 5DSP MK2
Huge power in a tiny format
Hardly bigger than a smartphone but a giant in performance with an incredible output power of 400/ 800 Watts RMS/ max. and five amplifier channels.
These amazing figures in such a tiny space result from Audiotec Fischers proprietary Class HD-technology, which guarantees an unrivaled efficiency and therefore minimum heat dissipation. Even better – this offers unimagined possibilites when choosing the mounting location.ACO – Advanced 32 Bit platform
The M 5DSP MK2 is the first MATCH amplifier equipped with our new, extraordinary powerful 32 Bit ACO platform. This provides higher speed during the communication with our DSP PC-Tool software, but also when switching between the 10 internal memory locations for sound setups. In addition, the ACO offers an integrated, channel-separated Input EQ and Input Signal Analyzer (ISA), e.g. for compensating any kind of equalizing in the factory radio.Latest DSP technology
The extremely powerful 64 Bit audio DSP with its seven channels offers in combination with the CoProcessor ACO amazing DSP sound features, like the “Augmented Bass Processing”, the “StageXpander” and the “RealCenter” function and thus completely new possibilities in sound tuning.Power on demand
That’s unique – the M 5DSP MK2 features two power modes, allowing it to run either in “HighPower” mode for maximum performance or in “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications without a separate power supply.Intuitive DSP PC-Tool
Such a bunch of technology must remain operable – our professional and user-friendly DSP- PC Tool software V4 impressively demonstrates that a huge feature set and an easy configuration can be perfectly harmonized. -
Helix C FOUR
Audiophile sound quality combined with impressive output power
The C FOUR is a high-end 4-channel amplifier that has been designed down to the last detail for ultimate sound quality. Audiotec Fischer’s proprietary ultra low-noise and ultra low-distortion Class A driver stage feeds a total of 32 hand-selected MOSFET power transistors, resulting in an incredible damping factor of 1,000 for relentless control of every loudspeaker. The intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power independent of the cars battery voltage.
In combination with the optionally available digital input module HDM 2, the C FOUR demonstrates the perfect transition to the digital era. The HDM 2 accepts digital audio signals up to 96 kHz sampling rate via its two optical inputs followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C FOUR is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.
